One of the most underrated family films here and at IMDb, but I understand why. Overall, this movie is a great family film - funny, charming, awesome set pieces, and they stuck (for the most part) true to the TV series. My kid loved this film, which I showed her right after ripping Cat in Hat out of the DVD player and chucking that trash across the room, much to my child's bewilderment. lol
See, my kid didnt grow up on Flintsones like I did, but I did download some episodes of the cartoon and she adores it, mostly coz of pebbles and the catchy theme music. So she was in her glory when the movie started and the same tune starts (although remixed nicely by the B-52s) and was hooked rest of the way. And it's a very watchable film even for the adults.
But coming back to why people bash on this film, i think nobody can ever please the crowd that believes classics such as the Flinstones should never be re-done, and going from cartoon to live action is always very tough to do, but I think the number 1 reason is that fat blob Rosie O'Donnell. Worst Casting Disaster Ever! Fred was perfectly cast as John Goodman, and even Wilma was great. Barney, well, Moranis has the voice, facial features, and height of Barney, but they should've made him put on at least 40lbs for this film or given it to someone else. But Rosie?? what the HELL was that? Both Bettie and Wilma were hotties, based on original series, and Bettie has a much better voice and nicer curves (as far as cartoon goes), so to get treated to Rosie O'Blob playing Bettie was too much for any Flinstones fan to swallow. If you block that out of your mind though, it's overall a great movie.
Who would I have chosen as Bettie? How about Twin Peaks star Sherilyn Fenn?
